The IQ is essentially the same. The XSi has a few more megapixels but it isn't really significant. Buy the one that feels better in your hand. 40D for long use and meaty feel, XSi for lighter weight and smaller hands.

I've been trying to decide between the same 2 cameras. They are relatively in the same price range but the XSI has received some great reviews. But Cannon is running a rebate ($200 I think) on the 40Ds until July 19th I believe. From the suggestions of the other posters, seems like the 40D is the better of the two.

I just picked up a XSI with the canon 10-22mm and I am in love with this setup, I have been having a blast... I dont think you can go wrong with either one, but I say XSI because I have it and I love it

Thanks man for posting the pics. I have been debating Canon XSI vs Nikon D60 for a week and reading too many mixed reviews. I am going to pick up XSI tomorrow.

Since no one responded to my thread I'm gonna jack this one.. Do you guys know if the XSI supports HDR photos? If so how do you enable it in the camera?

Not sure what you mean by 'supports HDR photos' since HDR pics are more than one pics, it's multiple pics of the same object with over- and underexposure, put together to one HDR pics in a photo program. And, yes, you can use you XSi to do that.

As for XSi or 40D, I like the size and feel of the 40D better than the XSi. And one other great feature of the 40D, is the navi wheel on the rear.

Oh never mind then i thought there was an option to shoot HDR straight out of the camera. Anyways I love it, the interface is very easy to use and understand and the live view mode is very useful. One complaint though is when you try to take a shot through the viewfinder, your nose touches the screen and it gets oily and shit.

I've had a 20D for 4 years and about 40K shots and just picked up an XSi this summer. My take is that the 40D vs. XSi question boils down to your expected application:

If you shoot action sports and thus need a quick frame rate and perhaps a bit better durability, the 40D is for you. Similarly, if you have big hands then the 40D will likely feel better to you. Indeed for me the small body and the fact that my pinky slips off the bottom of the grip is the biggest negative to the XSi. The 40D, like my old 20D, fits my hands much better.

That said though, the XSi will provide marginally better image quality at marginally lower cost. Particularly for long telephoto shooters like me, the higher pixel density of the XSi is a significant benefit. The fact that if you hunt you can pick up an XSi body for under $600 helps too.

In short, I tend to judge the body largely by the sensor and I believe the XSi to have a better sensor than the 40D.

What you are referring to is AEB , and yes XSI, XT, XTI, they all support it... and if you want a camera that doesnt have AEB, its not a big deal you can manuall play with the exposure settings. But AEB does make it easier.

However, all that will give you is 3 shots of different exposures. Then you need a program called photomatix to create HDR images.

HDR is played out, that over drawn look is whack. HDR is only good if you use it for the right reasons, and not to have extremely fake looking pics.

I needed it for lighting in a 3D program. I hate the look of HDRi photos too lol
